UNITED STATES PATENT OFFICE.

MATTIE A. R. LOWD, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN TOOTH-BRUSHES.

Specification forming part of Letters Patent No. 158,099., dated December 22, 1874; application filed May 26, 1874.

' sible, to thoroughly clean the various cavities and channels formed in the plate in which the teeth are set; and to provide a convenient and proper brush for the above purpose, in combination with a tooth-brush, and obviate all previous troubles, is the object of the present invention; and it consists in arranging bristles so as to project longitudinally from the extreme end of the handle of a common toothbrush.

In the accompanying plate of drawings my invention is illustrated, the figure representing a side view of a common tooth-brush with my invention applied to the handle.

A represents the handle; B, the bristles, secured to and projecting from one side of one end of handle A, as ordinarily; O, bristles, secured to extreme end a of handle A, and projecting from the handle in a line parallel, or nearly so, to the length of handle.

In cleaning sets of false teeth by the common brush as at present constructed by the bristles projecting at right angles, or nearly so, to the length of the handle, the end b of the handle interferes, more or less, to prevent the bristles from entering the cavities and channels, owing to the peculiar form and construction of the plate,-&c. but with the bristles secured in and projecting from the extreme end of handle, as at a, the end a of the handle is back from the bristles, leaving them entirely free to easily and readily penetrate and to thoroughly clean any cavity, &c., in the platea necessity for the better preservation of the teeth and plate and for the comfort of the person using them, especially in the matter of cleanliness; also, for the dentist in the manufacture, &c., of teeth and plates for the same my improved arrangement of the bristles, as hereinabove described, is very desirable, and in the combination with tooth-brush the necessity of two brushes is obviated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

As a new article of manufacture, a toothbrush provided with the bristles O, projecting longitudinally from the extreme end of the handle, substantially as and for the purpose specified.

The above specification of my invention signed by me this25th day of April, A. D. 187 4.
